Thanks in advance.
Automatically connecting host devices as they are plugged into the host is a policy decision, and has security implications too - QEMU will be forbidden to access any plugged devices due to sVirt and also file permissions. As such we delegate this tasks to applications using libvirt, and do not intend to do anything to have this automatic plugging done by libvirt or qemu itself.
